/**
 * {@link Viewer} plugin that loads lidar point cloud geometry from LAS files.
 *
 * &lt;a href=&quot;https://xeokit.github.io/xeokit-sdk/examples/index.html#loading_LASLoaderPlugin_Autzen&quot;&gt;&lt;img src=&quot;https://xeokit.github.io/xeokit-sdk/assets/images/autzen.png&quot;&gt;&lt;/a&gt;
 *
 * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/index.html#loading_LASLoaderPlugin_Autzen)]
 *
 * ## Summary
 *
 * * Loads [LAS Formats](https://www.asprs.org/divisions-committees/lidar-division/laser-las-file-format-exchange-activities) up to v1.3 from both *.las* and *.laz* files. It does not support LAS v1.4.
 * * Loads lidar point cloud positions, colors and intensities.
 * * Supports 32 and 64-bit positions.
 * * Supports 8 and 16-bit color depths.
 * * Option to load every *n* points.
 * * Does not (yet) load [point classifications](https://www.usna.edu/Users/oceano/pguth/md_help/html/las_format_classification_codes.htm).
 *
 * ## Performance
 *
 * If you need faster loading, consider pre-converting your LAS files to XKT format using [xeokit-convert](https://github.com/xeokit/xeokit-convert), then loading them
 * with {@link XKTLoaderPlugin}.
 *
 * ## Scene and metadata representation
 *
 * When LASLoaderPlugin loads a LAS file, it creates two {@link Entity}s, a {@link MetaModel} and a {@link MetaObject}.
 *
 * The first Entity represents the file as a model within the Viewer&apos;s {@link Scene}. To indicate that it represents a model,
 * this Entity will have {@link Entity#isModel} set ````true```` and will be registered by {@link Entity#id} in {@link Scene#models}.
 *
 * The second Entity represents the the point cloud itself, as an object within the Scene. To indicate that it
 * represents an object, this Entity will have {@link Entity#isObject} set ````true```` and will be registered
 * by {@link Entity#id} in {@link Scene#objects}.
 *
 * The MetaModel registers the LAS file as a model within the Viewer&apos;s {@link MetaScene}. The MetaModel will be registered
 * by {@link MetaModel#id} in {@link MetaScene#metaModels} .
 *
 * Finally, the MetaObject registers the point cloud as an object within the {@link MetaScene}. The MetaObject will be registered
 * by {@link MetaObject#id} in {@link MetaScene#metaObjects}.
 *
 * ## Usage
 *
 * In the example below we&apos;ll load the Autzen model from
 * a [LAS file](/assets/models/las/). Once the model has
 * loaded, we&apos;ll then find its {@link MetaModel}, and the {@link MetaObject} and {@link Entity} that represent its point cloud.
 *
 * * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/index.html#loading_LASLoaderPlugin_Autzen)]
 *
 * ````javascript
 * import {Viewer, LASLoaderPlugin} from &quot;xeokit-sdk.es.js&quot;;
 *
 * const viewer = new Viewer({
 *      canvasId: &quot;myCanvas&quot;,
 *      transparent: true
 * });
 *
 * viewer.camera.eye = [-2.56, 8.38, 8.27];
 * viewer.camera.look = [13.44, 3.31, -14.83];
 * viewer.camera.up = [0.10, 0.98, -0.14];
 *
 * const lasLoader = new LASLoaderPlugin(viewer, {
 *     colorDepth: 8, // Default
 *     fp64: false,   // Default
 *     skip: 1        // Default
 * });
 *
 * const modelEntity = lasLoader.load({
 *     id: &quot;myModel&quot;,
 *     src: &quot;../assets/models/las/autzen.laz&quot;
 * });
 *
 * modelEntity.on(&quot;loaded&quot;, () =&gt; {
 *
 *      const metaModel = viewer.metaScene.metaModels[modelEntity.id];
 *      const pointCloudMetaObject = metaModel.rootMetaObject;
 *
 *      const pointCloudEntity = viewer.scene.objects[pointCloudMetaObject.id];
 *
 *      //...
 * });
 * ````
 *
 * ## Transforming
 *
 * We have the option to rotate, scale and translate each LAS model as we load it.
 *
 * In the example below, we&apos;ll scale our model to half its size, rotate it 90 degrees about its local X-axis, then
 * position it at [1842022, 10, -5173301] within xeokit&apos;s world coordinate system.
 *
 * ````javascript
 * const modelEntity = lasLoader.load({
 *      id: &quot;myModel&quot;,
 *      src: &quot;../assets/models/las/autzen.laz&quot;
 *      rotation: [90,0,0],
 *      scale: [0.5, 0.5, 0.5],
 *      origin: [1842022, 10, -5173301]
 * });
 * ````
 *
 * ## Configuring a custom data source
 *
 * By default, LASLoaderPlugin will load LAS files over HTTP.
 *
 * In the example below, we&apos;ll customize the way LASLoaderPlugin loads the files by configuring it with our own data source
 * object. For simplicity, our custom data source example also uses HTTP, using a couple of xeokit utility functions.
 *
 * ````javascript
 * import {utils} from &quot;xeokit-sdk.es.js&quot;;
 *
 * class MyDataSource {
 *
 *      constructor() {
 *      }
 *
 *      // Gets the contents of the given LAS file in an arraybuffer
 *      getLAS(src, ok, error) {
 *          utils.loadArraybuffer(src,
 *              (arraybuffer) =&gt; {
 *                  ok(arraybuffer);
 *              },
 *              (errMsg) =&gt; {
 *                  error(errMsg);
 *              });
 *      }
 * }
 *
 * const lasLoader = new LASLoaderPlugin(viewer, {
 *       dataSource: new MyDataSource()
 * });
 *
 * const modelEntity = lasLoader.load({
 *      id: &quot;myModel&quot;,

 *
 * ## Showing a LAS/LAZ model in TreeViewPlugin
 *
 * We can use the `load()` method&apos;s `elementId` parameter
 * to make LASLoaderPlugin load the entire model into a single Entity that gets this ID.
 *
 * In conjunction with that parameter, we can then use the `load()` method&apos;s `metaModelJSON` parameter to create a MetaModel that
 * contains a MetaObject that corresponds to that Entity.
 *
 * When we&apos;ve done that, then xeokit&apos;s {@link TreeViewPlugin} is able to have a node that represents the model and controls
 * the visibility of that Entity (ie. to control the visibility of the entire model).
 *
 * The snippet below shows how this is done.
 *
 * ````javascript
 * import {Viewer, LASLoaderPlugin, NavCubePlugin, TreeViewPlugin} from &quot;../../dist/xeokit-sdk.es.js&quot;;

 * const viewer = new Viewer({
 *     canvasId: &quot;myCanvas&quot;,

 *     hierarchy: &quot;containment&quot;
 * });
